Stability of Orthotropic Runway Plate under The Combination In-Plane and Transversal Dynamic Loads on Kerr Foundation Soil Modelling

Abstract

Abstract Runway pavements are subjected to dynamic loads from aircraft landing and take-off, which can cause vibrations and lead to cracking and instability. The existing method for designing runway pavements, the ACN-PCN method, does not consider the effects of vibration, deflection, and external loads. This research proposes a new approach for designing runway pavements using a numerical method that accounts for these factors. The method uses differential and Kerr foundation equations with the Levy method to determine the deflection of the plate structure. The soil parameters are obtained from soil sampling, and the loads are designed based on previous studies and government regulations. The results of the research show that the soil characteristic has the greatest impact on the deflection of the plate. A harder soil will result in less deflection, which is important for the safe operation of the runway. A thicker plate also exhibits increased stiffness and reduced deflection. In-plane compressive loads can increase the potential for plate bending, which can compromise the structural integrity of the plate.
